This set is important for good quality 3D print. For getting the even print we should have to level the bed. For that first we need to place the print plate on the shelf and should align the tabes and the power magnet will lock the plate automatically.

Turn on the printer select the bed leveling option from the prepair tab. Display will show us to go to the next step.

Before begining the bed leveling process we should make sure that there should not any bebbering at the nozzel tip this is esential for getting proper layer hang.

We should also unlock all the levelling screws beneath the print plate. Fallow the direction on the display to go for the next step. Lock the screw at the pressed possition by the nozzel at three different positions. Now the bed leveling is done.

Now we will take the sheet of paper to calibrate the hight of nozzle. Place the sheet of paper between nozzle and bed.

Move the bed in the upward direction to move closer and closer to the nozzle. Slide the sheet of paper back and forth while turning the dial until we can feel slight friction form the nozzle. Then select enter on the display. In this way we have finished the calibration process of nozzle.

Adjust the distance between the nozzle and the print bed by selecting prepare and then autohome. The bed moves down to its original position and the nozzle to its hame position. Now heat the nozzle until the temperature required to sufficiently heat the material is reached then set the bed temperature and then we can give the print.

For remove the material from extruder, just heat the nozzle and hold the material at the upper side of extruder

Material holder is at the right side of the printer. We can remove it and change directly.

First we have to design our 3D model by using and 3D designing software. I have designed my handel using 'Fusion-360'.

I have clone the design file from in my operating system.Machine operates with programming language. So we have to convert our file in G-code.For that we have use 'factory' software for generating G-code.

In next step we have to convert our 3D object in the programming language, so I have open the file in Fractory software.We have to select name of our 3D printer from the list before processing the design file. We have 'Extended version of Julia' so I have select it and click on 'Add printer' option.

After cilcking on add printer option a 3D environment is opens on the screen as shown in the image below. Where we have first we have to call our object.

Then select material we are going to use for our printing here I am using ABS (is a thermoplastic polymer) , nozzel diameter, if we require we can also select the supports in our design.

And, finally click on 'Prepare' option to the left bottom side. Once we click on prepare over G-code is get created, it will ask to save the file. If we have connect our pendrive it will directlly get save in our pendrive.

When we create G-code of the 3D printed file, we can see the change in the color of blue.

Now we can give our 3D designe file to 3D printer, directlly by connecting the pendrive.

In the third image we can see the failed object because the printer was get stop due to power cu-off issue, before print is completed.

In the fourth image we can see the 3D printed handel. After our print is completed we have to cool the bade as in this stage our bade temperature is very heigh so that we can not remove our object very easily.We have to select the option of 'fan' from the temperature setting in our machine.

Once the temperature is reduces we can easily remove our object from the bade. I have given supports in my design file so I have to remove that support once our print is completed.

As we can see in the design I have provided the slot and the provision of mounting nut and bolt in my design itself. If we look at the surface of the handle it is fully solid I have provided the filets at the surface to remove the sharp corners. I have provided this for easy handelling of the user. Because where ever we install the handel if is subjected to Push and Pull forces. Therfore if the body of handel have this shape it is not get affected by these forces easily.

As the discription of the design mentioned above we can not made this easily with the subtractive method. Or if we tray it with subtractive method it takes more material and time for machining. For example if we want to made the same handel with subtracive method . To made this shape on CNC lathe invovles facing, turning...etc. Every time the machine need to change the tool. Also this process invovles lot of chip formation that means wastage of material.

Hence we can not made this handel with Subtractive method.

3D printers are affordable. 3D printing is a single step manufacturing process, so not only it saves the cost than other manufacturing processes and machines but also the time.

Using 3D printing equipment, we can create prototypes within a couple of hours. Due to which the design process speed is considerably increased.

Plastic is the primary material used in 3D printing, but metals are also used. 3D printing allows complex, organic shapes to be made that are much lighter than traditionally machined parts.

The use of 3D printing technology reduces the quantity of waste materials created during the production process. This technology is environment friendly since the lightweight 3D printed models made can make cars or aircraft significantly more fuel-efficient.

The use of 3D printing equipment has increased in recent years due to increased accessibility.

Usually the chamber size integrated into 3D printers is relatively small, which restricting the part sizes that you can print.

3D printed parts are typically created one layer after another, hence it is referred to as additive manufacturing. Therfore where the layers are not get bounded properly, they are subjected to splitting when exposed to loads at specific orientations or stresses. It is an issue that is often experienced with items created using fused deposition modeling (FDM).

3D printing technology is not very userfriendly. Because it is a new technology and it offen reqquires trial and error method when creating parts on a 3D printer.

3D printing technology is a recent innovation, therefore the materials needed during the manufacturing process are limited and some of which are still being developed.

It is now very easy for anyone to get the blueprint of the product to copy existing products quickly. Due to this there has been an increase in patent violation, and identifying a counterfeit product is almost impossible.

First go to the downloaded setup.

Then start to install it.

Select the required option. If we want to scan human then choose the human and if we want to scan any object then choose the object option

If we have selected the object then it will ask us that where we have to select small, medium or large object.

If we have selected human then the next question is whether we want a full body scan or a head only. For scanning my object I have choose the head option.

This is the object which I have desided to scane. It is a pot which we can used for tree planting. It is made by my local instructer Komal Raut during her fab academey.

For scanning this object have place it at the stationary possition and have adjusted the position of scanner.But in this technice the object is not get scanned properly and image with pixel is formed.

In the next turn we have place our scanner at stationary possition and movable object. This is the 3D image created in the software called '3D sense'.

This is the main window of 3D sense software. In which we can see the facility of save, upload, print. At the start it is blank. When we are scanning the object we can see it on the screen.

Now we can modify our object by using following commands, that if we wanted to fill the portion which is open we can solidify it by using these option and other options for modifing our print.

In the following image we can see some more modefing tools like color, trim, touch up. By using these option we can make our scanned object more attractive. Once we have done all the changes there are two options one is to go previous or next. Click on the next.

After our object is ready click on save option our file is get save in 'stl' format.

I have uploaded that 'stl' file on 'sketchfab' online uploading site and have given that link in my file to view my object in the 3D environment and also can move it.

After scanning I have printed my pot on 3D printer and again have follow the same procedure for printing that object.

This is the 3D object .So this is the mini-version of pot.

After scanning the above object I was very qurious about how we can scan the whole body of the human. Therfore I have scanned myself by using scanner and 3D sense software.

In this week we have studied the different parameters of 3D printer.

In last week we have learned about designing different 2D and 3D objects and in this week I have used that technique to develop 3D designing objects for 3D printing.

To print an object on 3D print there are two methods first is to design and give an .stl file directly to the 3D printer and second , when it is difficult to design the shape of object or if there is less time to design the object and if we require an object in the optimized form there we use scanner. Where we scan the object which we want to print on the 3D printer and will give the file to 3D printer in .stl format.

So, in this week I have printed Mini-me.
